The right to breathe freely is our most fundamental right. Oxygen is critical for life and fresh air is critical for good health. No one has the right to impede the breathing of another person, forcing them to wear a mask that requires them to breathe in their own respiratory waste and the pathogens that cling to the mask after it has been worn for a while. Some people with existing breathing or oxygen-related issues suffer considerably when forced to wear a mask. Also - masks don't stop the spread of viruses.
